Tactile and mechanical allodynia are symptoms experienced by many patients suffering from different pathology especially from neuropathy.  In patients with post-traumatic / postsurgical neuropathic pain, different methods were performed to evaluate tactile and mechanical allodynia. In rat, different models such as Chronic Constriction Injury (CCI) and Spared Nerve Injury (SNI) mimic neuropathic pain symptoms.  The objective of pharmacological labs is to develop new antalgic to treat this specific pain and a growing need is observed in in vivo models of neuropathic pain but also in relevant tests able to detect the small variation of pain and especially tactile allodynia. The objective of this study was to assess the tactile and mechanical allodynia in rat models of neuropathic pain using manual and electronic of von Frey.
